Ikki was once a member of a violent biker gang; but when he encounters an innocent but determined young man who's ready to risk his life to protect the small ramen shop he had established through his own efforts, he immediately falls in love with him and vows to stay by his side.
But by a cruel twist of fate Mari passes away, leaving Ikki to manage the eatery on his own while struggling to put the memories behind him; all of which is made infinitely more difficult by his terrible cooking skills, his clumsiness, and the fact that he has two children to care for.

Shou works in a delivery service that makes regular drop-offs at Mari's, and it doesn't take him long to become infatuated with Ikki. But things don't look too good for him; after all, the object of his affections is still firmly clinging to feelings for his deceased beloved while being locked in a battle of wills with Saneatsu -- Mari's wealthy and arrogant elder brother from whom he had been estranged long before his death -- who has now taken to frequenting the establishment and threatening to have it pulled down. Much to Shou's dismay, Ikki doesn't seem to see him as anything more than an acquaintance and a business associate.

It only becomes more complicated once Shou's partner Rikiya is thrown into the equation; casual and friendly exterior notwithstanding, he is very much in love with the utterly oblivious Shou...
